What happened when researchers tested one million Amino Acid to base pairs? -
Answer-The Natural Code that is the current Amino Acid to base pairs is the smallest
effect on polarity with a mutation amongst the millions of different combinations. = - D
Key Point #13 - Answer-The genetic code evolved to minimize the effect of each
mutation on the phenotype.
True or False? Biodiversity on Earth will likely decrease in the near future. - Answer-
False
True or False? Scientists believe in evolution even though they currently lack evidence
for the theory. - Answer-False
Opposition to irrational numbers was based on evidence that such numbers cannot
exist. - Answer-False - (No direct evidence for or against irrational numbers was used to
oppose the idea. A religious belief based on faith was used instead.)
Opposition to irrational numbers stemmed from a worldview involving naturalistic
evolution. - Answer-False - (A creationist worldview was the reason for opposing
irrational numbers.)
The belief that irrational numbers cannot exist reflects religion more than science. -
Answer-True - (The notion that God(s) created a perfect world is the product of a
religion)
Modern mathematicians accept irrational numbers because such numbers provide more
accurate solutions to problems than whole numbers do. - Answer-True - (irrational
numbers are used because they enhance calculations of measurable properties, such
as the area of a circle).
The scientific method relies on ____________.
models
observations
experiments
all of the above - Answer-all of the above
,A model is a formal description of a scientific hypothesis. Which of the following types of
models provides the most precise description of a hypothesis?
verbal
graphical
mathematical
All of the above are equally precise - Answer-mathematical
An experiment enables one to demonstrate that a correlation between two variables
results from cause and effect.
True
False - Answer-True
A well designed experiment ____________.
a. controls for environmental and genetic factors.
b. involves replication of experimental subjects.
c. randomizes experimental subjects among treatments.
d. achieves all of the above. - Answer-d. achieves all of the above.
Biologists used induction to hypothesize that snakes use pits to see heat. - Answer-True
Biologists used induction to predict the percentage of times that a snakes with sealed
pits would choose the cool box. - Answer-False
Each treatment (sealed pits vs. unsealed pits) was replicated 20 times. - Answer-False
The experiment would be flawed if snakes were not randomly assigned to each
treatment. - Answer-True
The group of snakes whose pits were left unsealed served as a control in this
experiment. - Answer-True

More than a decade after Darwin returned from his voyage on the HMS Beagle, an
explorer named Alfred Wallace voyaged to the Malay Islands. Wallace was struck by
the biodiversity of the islands. In particular, he noticed animals with structures designed
to attack plants, and plants with structures designed to protect them from animals.
Wallace reasoned that differences among individuals provided advantages that
gradually led to evolution. He immediately sent a manuscript describing his idea to
Charles Lyell, who then shared the manuscript with Darwin. Wallace's model of
evolution by natural selection was published a paper that appeared in the same issue
as Darwin's paper.
, Unlike Wallace, Darwin did not believe that natural selection required variation among
individuals. - Answer-False
Wallace used induction to develop a model of evolution by natural selection. - Answer-
True
Unlike Wallace, Darwin's conceived his theory of evolution without observing species
living on islands. - Answer-False
Both Darwin and Wallace must have assumed that differences among individuals were
passed onto their offspring. - Answer-True
Similar to Wallace, Darwin conceived a theory of evolution by natural selection while
voyaging around world. - Answer-False
Both Wallace and Darwin adopted a worldview described as either naturalistic evolution
or theistic evolution. - Answer-True
Use this information to answer the questions below.
In certain populations in Africa, people who drink cow's milk suffer from cramps and
diarrhea. This condition results from an inability to digest lactose, the major
carbohydrate in milk. Interestingly, these people belong to tribes that historically
consumed grains produced by agriculture, instead of drinking milk from domesticated
animals. In other parts of Africa, the majority of people can drink milk without suffering
any negative effects. These people belong to tribes that historically relied on milk from
domesticated animals for nutrition.
The ability to digest milk likely varies genetically between African populations. - Answer-
True
The ability to digest milk likely conferred a reproductive advantage in populations that
relied on cows for nutrition. - Answer-True
Natural selection likely generated the variation in lactose tolerance among populations
of Africans. - Answer-True
If biologists sampled a population of Asians who never relied on cows for nutrition, the
majority of them likely digest lactose without difficulty. - Answer-False
Lactose tolerance likely depends on genetic variation that one could artificially select. -
Answer-True
In cats, white fur results from a gene that codes for tyrosinase, an enzyme that
catalyzes the production of pigment. A mutation in this gene creates an allele coding for
